Cable Gland positions/ cable run advice

[aitchem]

Hi,
Renovation continues on my Sadler 27.
I am looking for constructive advice regarding gland position on the deck.
From what I have seen in the marinas, most cables run up through the deck into the top tube where it runs into the deck, then out through a hole drilled into the bottom of the tube.

Is it possible to take off the steelwork and go up directly into the foot/base.?
Has anyone done this.?
Any useful suggestions welcomed.

thanks
Howard

Yes, I've worked on a boat with the nav light wiring going up through the bas of the pushpit/pulpit and exiting through a hole in the underside of the tube where required. The only problem is getting it there - rather thn branching off down some other route. I guess one would push a mouse/rod up until by good chance you arrive at the exit hole, then pull a cord down ready to pull the wire into place. Might help feeding the wire into place if you spray with teflon dry lubricant or silicon grease.

My boat (Centaur) does this, as do quite a few boats. Does mean that you have to take pulpit off and drill hole in deck and possibly loosen headlining, if any. You may also not be able to push a wire through the tubing to where you want it.
Same comments about the pushpit, except for headlining.

I did find it a problem when I replaced the wiring. Would have liked to have gone up a size but restricted by the size of the entrance to the tubing.

Thanks guys,

I'll see if I can get the steelwork off first.
These bolts haven't been touched in 32 years.!

There must be some kind of lever type screwdriver.

Personally would not bother if the current steelwork is well sealed. It will almost certainly spring out of shape when you take it off and you run the risk of not resealing properly when you put it back. Use the small Index Marine thrudecks and attach the cables to the tubing with cable ties. Neat, easy to replace and seal.

When you get to trying to feed wires through the tube, you might do worse than use a long length of the fine chain that is used for bath plugs etc.
It has some weight, is very flexible and some strength for pulling an attached following wire.
I used this chain to feed a thin wire inside a 1920's art nouveau lamp- nothing else worked, since it had to go round 2 internal angles to get to the lamp holder. It took some patience but was well worth the effort.
As far as your steelwork is concerned, just hope they used the same grade of steel on the below deck attachments....
